Step 1
Create a preliminary base and lay it flat on the table, with the closed tip pointing at 12 o’clock.
Step 2
Make a diagonal valley fold by bringing the lower right edge of the right front flap from right to left along the vertical axis of symmetry.
additional information
- To locate the axis, you can lift the left front flap vertically.
Step 3
Make a diagonal valley fold by bringing the lower left edge of the left front flap from left to right along the vertical axis of symmetry.
additional information
- You will obtain a front flap in the shape of a kite.
- This flap has two triangles folded toward the vertical axis of symmetry.
- The upper edges of these two triangles form a horizontal line with some overlap.
Step 4
Make a valley fold along this horizontal line, bringing the top closed point down onto the vertical axis. Crease well because there are multiple layers, then unfold.
Step 5
Unfold the two triangles of the front flap.
additional information
- You will return to the preliminary base, on which you can see two diagonal valley folds starting from the bottom point and reaching the top edges of the two front flaps, at the level of a horizontal valley fold.
Step 6
Begin a petal fold. To do this, hold the first layer of the bottom point between your thumb and forefinger.
Lift this point until it is aligned above the horizontal valley fold.
additional information
- As you do this, the left and right points of the model will rise naturally, and the two oblique valley folds (coming from the second layer of the lower point) will begin to fold on their own.
Step 7
Complete the petal fold. Continue lifting the point upward until it lies completely flat.
At the same time, with your other hand, continue folding the lower oblique valley folds, bring the side points back onto the vertical axis, and flatten the upper oblique folds that form (the former valley folds now becoming mountain folds).
Ensure all folds are sharply defined.
additional information
- You obtain a front flap in the shape of a vertical diamond, with the lower point locked inside the fold while the upper point remains free.
Step 8
Turn the model from right to left.
additional information
- You now have a front flap in the shape of a square, in a diamond orientation, partially covering the elongated diamond formed in the previous step.
- The vertical axis of symmetry is a valley fold.
- A horizontal mountain fold crosses this axis and connects the two upper edges of the square.
Step 9
Repeat the manipulations described in steps 2, 3, 4, 5, 6, and 7.
additional information
- At the front of the model, you obtain a vertical diamond that perfectly overlaps the diamond underneath.
- The bird base is ready.
- The model has a diamond shape in a vertical position.
- The lower part forms a triangular structure built around two independent symmetrical triangles of quadruple thickness, separated by a vertical slit.
- The upper half contains three overlapping triangles:
- at the front, a large double-thick triangle with a slit at the top along the vertical axis;
- in the middle, a small quadruple-thick triangle with a closed top point;
- at the back, a large double-thick triangle with a slit underneath along the vertical axis.
- There are nine points in total:
- a lower left point,
- a lower right point,
- a front left point,
- a back left point,
- a front right point,
- a back right point,
- a front top point,
- a middle top point,
- and a rear top point.
